*** Next ***
- NEW: Added support for LDM303AGR 6 axis Accelerometer\Magnetometer MEMS.
- NEW: Added support for LSM6DSL 6 axis Accelerometer\Gyroscope MEMS.
- NEW: Added support for LPS22HB 2 axis Barometer\Thermometer MEMS.
- NEW: Separated OSLIB from RT and NIL, now it is a separate "product" with
       its own version, configuration file and licensing. The library will
       grow to include more functionalities.
       RT and NIL will contain only the core functionalities, everything else
       is shared library code.
